APPARATUS FOR SOLDERING CHAIN-LINKS.

Specification of Letters Patent. Application filed July 11, 1907. Serial-No. 383,361.

Patented June 16, 1908.

To all whom it may concern: Be it known that I, MAX FESSLER, a subect of the German Emperor, residing at Pforzheim, Baden, German-Empire, have invented certain new and useful Improvements in Apparatus for Soldering Chain-Links, of,

which thefollowing is a specification.

In the manufacture of chains, more especially ornamental chainslof all kinds, from wire furnished with a core of solder, a process has been proposed, acoordin to whlch the links are immersed in a ture, the crystals of the deoxidizing agent, with the exception of those at the actual joints,

from getting chain is coated with a protective mass, prior to being heated to melt the solder core and thus shut the joints of the links. My invention relates to apparatus for carrying out' 'such a process.

In the accompanying drawing-Fi ure 1 is i 2 is a plan thereof. Fig. 3 is a section on th e line AB of Fig. 2.

lfhe chain 6, whose unsoldered links are of solder cored wire, is wound upon the drum 0,, fromwhich it is slowly drawn in the direction of the arrow by passing between two off the main shaft d by means of friction wheels 0, to, counterpasses below two guide pulleys is, Z located in a tank m, filled with a soldering fluid (deoxidizing a ent). Here the faces of the joints to be solfered are sufficiently lpsickled or etched, and the surface of thelin adequately cleansed. The chain then passes over a second pair of guide pulleys n, O and thence under a guide pulley p direct through the pipe 1* burner apparatus g, whereby the. solvent is 'solderin salts is evaporated.

' In or er toremovethe dry crystals of the soldering salt from the links, except at the joints to be soldered, the chain is led through the eyeS of a crank r'od t, which works between two eyesu, V. This rod t'is actuated deo xldizing solution and after evaporation of the adhering moisremoved, whereupon, to prevent the soldered together, the,

h. The roller g is mounted gearing On leaving the heated by a Bunsen that is, thewater added to the by the disk crank W (which also constitutes a friction wheel) mounted on the shaft C, and receives guidancefrom a slide block reciprocatingin guides X. Owing to the rotary and advancing motion of the chain,. the hnks rub and scrape against each other and against the eyes a, V, so that the crust of saltis rejoints are not affected by this treatment.

under two like pulleys Z, 1, located in a tank 3, and up over a fourth pulley 2. The tank 3' contains a suitable protective mass which tends toprevent'soldering, and the chain 18 moved to and fro in thelnass by being passed through the slot' 5 ina rod 4 having anoscillatory motion. The rod 4 is suspended so as to swing at the point 6, and receives its oscillatory motion by means of a crank rod which is operated by a disk crank on the shaft 0 and is guided by'the slide block and guides 7, in the same manner as the crank rod :5. brought into intimate connection with the protective mass and all parts of the links, including the joints,.get coated ov'erwith a film is then conducted further by means of a second pair of rubber rollers 9, 10, the latter of which is mounted on a shaft which is also driven off the counter shaft C with the aid of shafting and bevelgearing I, 8. After passing the rollers 9, 10 the chain drops by ravity and passes at a suitable speed throng the flame of a Bunsen burner, or a soldering furnacel 1, or in the event ofstout links, through a blowpipe flame, which heats the links to such extent that the solder they contain is melted and shuts the jointsin a well-known manner.

Having thus described I claim as new is Apparatus for continuously shutting the joints of the links of a chain of solder cored wire, comprising in combination, a vessel of soldering fluid, a heating contrivance, two

my invention, what having been drawn through said fluid and exposed to heat, means for imparting a rota-ry motion In this way the various links are which is sufficient to prevent the links becoming soldered one to the other. The chain eyes through which the chain passes after A to the piece of chain for the time I moved from the surface, while the actual .60v The chain then passes over a guide pulley y,

Q assess being located between said eyes, a air of rollers for drawing the chain through 't 6 said apparatus, a vesselvof rotective materia1,,-.a

, second pair of rollers or drawing the chain.

through said material, and means'for heating the chain for the purpose of-ineltingthe core, substantially as described.
